replaced headlights now im getting an error code p1193
alright. so i just changeed my headlights but i had to remove the air box to get one of the headlgiht bolts out. and after installing new headlights and replacing the air box, im getting an error for the inlet sensor which i hooked back up the exact way it was before i took it out., and now the check engine light is on... the car was fine before heasdlight installation and still drives fine and sounds fine. but im just wondering if anyone has any ideas as to why it says error p1193 and how to get rid of it.... also have error p1684 which is the battery has been removed in the last fifty starts..... any ideas...? its got me baffled and i dont really want to drive it if the check engines on....
